Measuring Guide Penis Size

Choosing the correct size bathmate pump is important in order to maximize the effectiveness of the pump.

A pump that is too large for you could reduce vacuum pressure and consequently lead to less effective use.

Refer to the guidelines below on how to measure your penis correctly.

Step 1: Get An Erection

In order to measure yourself correctly your penis must be in an erect state. This will provide the most accurate method of ensuring you choose the correct pump.

You will then be able to select a pump from the four ranges provided.

Step 2: Measure Your Penis

Record the measurement from the pubic bone right up to the tip of your penis.

Measure your erect penis with a rule pressed lightly onto your pubic bone. You`ll find using a measuring gauge is easier than a ruler.

Record the measurement from the pubic bone right up to the tip of your penis.

It is very important to ensure you choose the correct size pump in order to maximize your gains. Choosing a pump that’s too large for you could reduce vacuum pressure and consequently lead to less effective workouts.
